Detailed Description

Function Documentation

static inline int hwloc_bridge_covers_pcibus ( hwloc_obj_t  bridge,
unsigned  domain,
unsigned  bus 
)
static
static inline hwloc_obj_t hwloc_get_hostbridge_by_pcibus ( hwloc_topology_t  topology,
unsigned  domain,
unsigned  bus 
)
static

Find the hostbridge that covers the given PCI bus.

This is useful for finding the locality of a bus because it is the hostbridge parent cpuset.

static inline hwloc_obj_t hwloc_get_next_bridge ( hwloc_topology_t  topology,
hwloc_obj_t  prev 
)
static

Get the next bridge in the system.

Returns
the first bridge if prev is NULL.
static inline hwloc_obj_t hwloc_get_next_osdev ( hwloc_topology_t  topology,
hwloc_obj_t  prev 
)
static

Get the next OS device in the system.

Returns
the first OS device if prev is NULL.
static inline hwloc_obj_t hwloc_get_next_pcidev ( hwloc_topology_t  topology,
hwloc_obj_t  prev 
)
static

Get the next PCI device in the system.

Returns
the first PCI device if prev is NULL.
static inline hwloc_obj_t hwloc_get_non_io_ancestor_obj ( hwloc_topology_t topology  ,
hwloc_obj_t  ioobj 
)
static

Get the first non-I/O ancestor object.

Given the I/O object ioobj, find the smallest non-I/O ancestor object. This regular object may then be used for binding because its locality is the same as ioobj.

static inline hwloc_obj_t hwloc_get_pcidev_by_busid ( hwloc_topology_t  topology,
unsigned  domain,
unsigned  bus,
unsigned  dev,
unsigned  func 
)
static

Find the PCI device object matching the PCI bus id given domain, bus device and function PCI bus id.

static inline hwloc_obj_t hwloc_get_pcidev_by_busidstring ( hwloc_topology_t  topology,
const char *  busid 
)
static

Find the PCI device object matching the PCI bus id given as a string xxxx:yy:zz.t or yy:zz.t.
